Abstract: The invention relates to a method for preserving foodstuffs, with which method foodstuffs are inoculated with an amount of lactic acid-forming bacteria and/or parts of bacteria and these bacteria and/or parts of bacteria act on said foodstuffs. Preferably, the action is allowed to proceed until the pH has fallen below 5. As a result of the use of this method an improved shelf life of the foodstuffs is achieved without pasteurisation or sterilisation being required. At the same time, the method guarantees a good retention of the taste of the products. A rapid growth of the lactic acid bacteria occurs in the method, as a result of which adverse organisms are denied opportunity for growth.

Abstract: A method of detecting a partially deflated pneumatic tyre on a vehicle having four tyres each mounted on a wheel comprising sensing the angular velocity of each wheel by providing for each wheel, a signal generator to provide a single signal or pulse for each turn of the wheel, characterised by selecting a first wheel and measuring the time for one rotation of that first wheel, after beginning said first measurement similarly measuring the times of rotation for each other wheel, storing the times for each of the wheels for at least three rotations of each wheel and averaging the times to produce an average angular velocity value for each wheel, processing the four signals in a processor unit which subtracts the sum of the signals from one pair of diagonally opposite wheels from the sum of the signals from the other pair of diagonally opposite wheels, sensing when the magnitude of the result is between 0.05% and 0.60% of the mean of the two sums and when it is operating a warning device to indicate a tyre is partially or completely deflated. 
     The method may also compare the signal of each wheel in turn to the average of all four to determine which wheel is deflated.

Abstract: The present invention relates to a method of forming a homogeneous ceramic coating on a substrate. The method comprises depositing a preceramic coating on a substrate and then heating the substrate while directing a stream of cooling gas at the surface of the preceramic coating such that a temperature gradient is developed in the coating. This temperature gradient is created in such a way that the preceramic material near the substrate is converted to its ceramic form while the preceramic material near the surface of the coating is deterred from conversion. The temperature gradient is then decreased over time such that all of the preceramic material ceramifies from the substrate outward to form a homogeneous coating on the substrate.

Abstract: A structured layer (12b) is to be produced by the method from a predetermined material with at least one recess (7) on a substrate (2), if necessary structured, using a high-temperature superconducting material. According to the invention, a lacquer layer soluble in a first solvent and having a structure corresponding to that of the layer (12b) to be produced is first applied to the substrate (2). An auxiliary layer, soluble in a second solvent, is then cold-deposited. The lacquer layer with the portion of the auxiliary layer which lies on it is then removed again by a lift-off technique by means of the first solvent, and the remaining construction is provided at an elevated deposition temperature with a coating layer of the material of the layer (12b) to be produced. Finally, the remaining portion of the auxiliary layer in the region of the recess (7), with the portion of the coating layer which lies on it, is removed by a lift-off technique by means of the second solvent.
